title = "Nonblocking WDM switching networks with full and limited wavelength conversion",
abstract = "In recent years, with the rapid exhaustion of the capacity in wide area networks (WAN) led by Internet and multimedia applications, demand for high bandwidth has been growing at a very fast pace. Wavelength division multiplexing (WDM) is a promising technique to utilize the huge available bandwidth in optical fibers. We consider efficient designs of nonblocking WDM permutation switching networks. Such designs require nontrivial extensions from the existing designs of electronic switching networks. We first propose several permutation models in WDM switching networks ranging from no wavelength conversion, limited wavelength conversion, to full wavelength conversion, and analyze the network performance in terms of the permutation capacity and network cost such as the number of optical crossconnect elements and the number of wavelength converters required for each model. We then give two methods for constructing nonblocking multistage WDM switching networks to reduce the network cost.",
